(30%) 3. A cantilever beam is used as part of a machine element carrying a load of
10,000 lbs at its end as shown in the figure below. In practice, however, the
deflection at the end point was observed to be excessive. A designer suggested
using a support at point B. The effect of the support is that the deflection at
point B will be zero. In order to design the support structure, we need to
determine the force provided by the support. Please use Castigliano's theorem
to find this force and neglect transverse shear.
